I have a 2002 max gle. I tried to "burp" trapped air from my radiator and here's what happened. Took the rad cap of, turned the heat on and ran the car until the cooling fans came on, coolant got sucked down into the radiator.
Then i turned the heat off. The coolant did not go anywhere in fact it started to spill out of the radiator. The only time it went down is when I had the heat on in the car. Is this normal? Even with the heat off, shouldn't the thermostat still open and allow coolant to flow thus the level in the radiator should go down and not spill out?
